Subject: Make name resolution thread-safe

* pthread/pt-alloc.c (initialize_pthread): Reset resolver state.
* pthread/pt-create.c: Include <resolv.h>.
(entry_point): Update the __resp TLS variable to point to the resolver
state of the current thread.
* pthread/pt-internal.h: Define __need_res_state and include <resolv.h>.
(struct __pthread): New `res_state' member.
